Iqhaza Lokushintsha Kwe-Plate-Mounted Kumakhibhodi Mechanical

Ezindaweni zamakhibhodi oomshini, indlela yokukhweza yamaswishi idlala indima ebalulekile ekunqumeni ukusebenza, ukuzwa, nokuqina kwekhibhodi. Izitayela ezimbili ezijwayelekile zokukhweza, i-PCB nokukhwezwa kwamapuleti, kunikeza izinzuzo ezihlukile nezici ezibhekelela okuthandwa ngabasebenzisi abahlukahlukene. Kulo mhlahlandlela obanzi, sihlolisisa umehluko phakathi kwe-PCB nokukhwezwa kwamapuleti, sihlola ukwakheka kwakho, ukufakwa, nomthelela ekusebenzeni kwekhibhodi.

Izinkinobho zekhibhodi ezifakwe epuletini zisancike ekukhetheni kwe-PCB njengokunemba kwezinyawo, i-hot-swap socket clearance, kanye nokusekelwa kwe-solder joint, ngakho-ke ipuleti lomshini kufanele lihlolwe kanye nemithetho yokuhlelwa kwe-PCB kanye nendlela yokugcina yokuhlanganisa i-PCB yekhibhodi.

Umehluko Oyisisekelo Ekukhwezeni

Umehluko oyinhloko phakathi kwe-PCB nokukhwezwa kwepuleti usenomboloni yezimbobo ebhodini lesekethe eliphrintiwe (PCB) kanye nokucushwa kweswishi okuhambisanayo. Amaswishi afakwe ku-PCB afaka izimbobo ezinhlanu ku-PCB ukuze kufakwe izikhonkwane zazo ezinhlanu: izikhonkwane ezimbili zensimbi zokuxhunywa kwamaswishi nezikhonkwane ezimbili eziseceleni zepulasitiki zokuzinza, nephinikhodi emaphakathi esebenza njengegayidi yokufaka. Ama-Plate-Mounted Switches, ngakolunye uhlangothi, anezikhonkwane ezintathu kuphela—ezimbili zokushintshwa kwemishini kanye nesisodwa esiqondisayo ngesikhathi sokunyuswa kwe-PCB—okuholela kuma-PCB aklanyelwe ukukhwezwa kwamapuleti anezimbobo ezintathu.

Lo mehluko obalulekile ezindleleni zokukhweza ubeka indlela yokufaka kanye nokuzinza okuphelele nomuzwa wekhibhodi. Amaswishi afakwe ku-PCB agitsheliswa ngokuqondile ku-PCB, ahlinzeka ngenqubo yokufaka elula enezimbobo zokulungisa amaswishi. Iphinikhodi isiza ukuqondanisa phakathi nokufakwa, okuholela ekuthinteni okulula kwekhibhodi kodwa okunamandla okuvumela ukugxusha kokhiye okwengeziwe, ikakhulukazi okulungele amakhibhodi amancane adinga ukuguquguquka okuncane nokuhlelwa kosekelo.

Ukushintsha Kwe-Plate-Mounted, njengoba igama labo liphakamisa, kudinga ipuleti elisekelayo ukuze lizinze. Ngamaphini amathathu kuphela, la maswishi ancike epuleti lensimbi elengeziwe ukuze agweme ukuntengantenga phakathi nokucindezela okhiye. Inqubo yokukhweza ipuleti ihlanganisa ukulungisa amaswishi epuletini ngaphambi kokuwathengisa ku-PCB, kuhlinzeke ngokuhlanganisa ikhibhodi eqinile futhi evikelekile. Nakuba ukukhwezwa kwamapuleti kungeza ubunkimbinkimbi nezindleko ngenxa yezingxenye ezengeziwe nezimfuneko zokuhlanganisa, kunikeza ukuzinza okuthuthukisiwe, okuwenza afaneleke kumakhibhodi amakhulu athambekele ekushintsheni, ikakhulukazi ngaphansi kokuthayipha kanzima.

Umthelela Ekusebenzeni Nokuzwakala Kwekhibhodi

Ukukhetha phakathi kwe-PCB nokukhwezwa kwepuleti kunomthelela kakhulu ekusebenzeni nomuzwa wekhibhodi. Ukushintsha Kwe-Plate-Mounted, ngenxa yokuqina okungeziwe okunikezwa ipuleti, kunikeza ukusebenza okuzinzile okunomuzwa ohlukile womunwe kumaswishi, okuholela ekubhaleni okuncane okungamatshe. Ukwesekwa okwengeziwe okuvela kupuleti kwenza amakhibhodi afakwe kumapuleti ahlale isikhathi eside futhi ahlale isikhathi eside uma kuqhathaniswa namakhibhodi afakwe ku-PCB.

Ngokuphambene, amaswishi afakwe kwi-PCB, nakuba elula futhi ebiza kakhulu, angase abonise ukuguquguquka okwengeziwe kanye nokugxuma kokhiye, ikakhulukazi kumakhibhodi amakhulu. Kodwa-ke, amakhibhodi afakwe ku-PCB kulula ukuwashintsha nokwenza ngendlela oyifisayo, okuwenza athandwe abasebenzisi abafuna ukucushwa kwekhibhodi okuguquguqukayo nokuguquguqukayo. Ukwengeza, amaswishi afakwe kwi-PCB ahambisana namakhibhodi ashintshashintshayo ashisayo, okuvumela ukushintshwa okulula nokwenziwa ngokwezifiso ngaphandle kokusoda.

Ukucatshangelwa Kwabakhi Bekhibhodi Nabashisekeli

Uma wakha noma wenza ngendlela oyifisayo ikhibhodi yomshini, ukuqonda umehluko phakathi kwe-PCB nokukhwezwa kwamapuleti kubalulekile ukuze kuzuzwe ukusebenza okufunayo nomuzwa. Nakuba ama-switch-mounted-mounted switches enikeza ukuzinza nokuqina okuphakeme, eza ngezindleko eziphakeme kanye nobunkimbinkimbi bomhlangano. Amaswishi afakwe kwi-PCB, ngakolunye uhlangothi, abiza kakhulu futhi kulula ukuwalungisa, okuwenza afaneleke kubasebenzisi abafuna ukwenza ngokwezifiso kanye nokusebenza ngezindlela ezihlukahlukene.

Sekukonke, ukukhetha phakathi kwe-PCB kanye nokufakwa kwepuleti kumakhibhodi omshini ekugcineni kuncike kuzintandokazi zomsebenzisi zokuqina, ukuzizwa, kanye nezinketho zokwenza ngokwezifiso. Ngokuqonda umehluko phakathi kwalezi zitayela zokufakwa, abathandi bekhibhodi bangenza izinqumo ezinolwazi zokudala ikhibhodi ehlangabezana nezidingo zabo ezithile kanye nezintandokazi, okuqinisekisa ulwazi lokuthayipha olugculisayo.

Ngokuhlela ukukhiqiza, kuyasiza futhi ukuqhathanisa lesi sihloko nezingxenye zebhodi lesifunda kanye nokukhethwa kwe-PCB laminate ngaphambi kokuqedela iphakheji yokwenziwa noma yokuhlanganiswa.
